| | :The double effect of high speed multicycle impact,speed and load fluctuant characteristics is the key factors influencing on wear resistance and multicycle impact resistance for the high speed automotive chain.The main wear mechanism of high speed roller chain is formation and propagation of crack in top layer of pin and bush.The roller must have sufficient strength and plastic.Rolling up is a suitable process for roller. | | 高速多冲以及速度与载荷交变特性的双重效应 ,是影响汽车用高速滚子链耐磨性和多冲抗力的关键因素。汽车用高速滚子链的主要磨损机制是销轴、套筒零件表层的裂纹生成、扩展与剥落。保证滚子零件具有足够的强度与塑性并采用卷制成形工艺是提高滚子零件多冲抗力的有效方法 | | 文摘来源 | | The high-speed and multicycle impact characteristics of an automotive chain differ from other high-speed roller chain. The double effect of multicycle impact characteristics and speed, load fluctuant characteristics set up a stern claim of wear to automotive chain. Influence of speed and load fluctuant characteristics is most important of all. Exceed the load-carrying resistance and wear resistance for top layer of pin and bush, resistance to plastic deformation for centre of ... | | 汽车链条的高速多冲特性不同于其它高速滚子链 ,高速下的多冲特性以及速度与载荷交变特性的双重效应 ,对其耐磨性能提出了苛刻的要求 ,而速度与载荷交变特性的影响尤为重要。销轴、套筒零件表层的抗多冲过载能力和抗多冲磨损能力以及心部的抗塑变能力和表层的循环软化与硬化特性是汽车用高速滚子链摩擦学设计的关键因素 | | 文摘来源 | | The fatigue lifetime distribution pattern of the automotive chain 06BT was studied experimentally.The results showed that its lifetimes under high stress test conditions comply with Weibull distribution with two parameters,the form parameter and the measure parameter which augment with the test load.The sampling test by accelerating test at load level(0.3)0Q can save time 14% in comparison with that at normal load level(0.25)Q,and the test at 0.33Q save time 25% than test at level 0.25Q.The SEM ... | | 研究了汽车链06BT的疲劳寿命分布规律,阐述了在所进行的高应力试验条件下,其疲劳寿命服从两参数的威布尔分布,并且其形状参数和尺度参数随载荷的增大而增大。加速试验(0.30Q载荷水平)的抽样检验比正常载荷(0.25Q载荷水平)节省时间14%,加速试验(0.33Q载荷水平)的抽样检验比正常载荷(0.25Q载荷水平)节省时间25%。由断口形貌(SEM)照片可以看出,汽车链06BT在0.25Q载荷水平的断口比在0.40Q载荷水平时的断口平滑得多。 | | 文摘来源 | |   | | << 更多相关文摘 |
